Well, I have been very frustrated with the process of buying things through him (though to be fair, it was always a BAT item that I had problems with.
Joe's very nice and personable... and he relays the explanations he gets to you. However, at the end of the day, I don't think he rides the process hard enough to get it done.
I still can remember the rear sway bar that was 4 1/2 months late, supposedly because the production was delayed that long... and they put up with it.
